SJB offers a bet against high-yield bonds. The fund delivers the inverse (-1x) of daily returns of a high-yield USD-denominated bond index that comprises issues ranging between 3 and 15 years to maturity. However, the daily reset will prevent the inverse relationship from holding true for more than one day. As a levered product with -1x factor that resets daily, SJB is not a buy-and-hold investment and should not be expected to provide index leverage return greater than a one-day period. Over longer periods, returns can vary significantly from -1x exposure to its underlying index. Holding it for a period longer will introduce the effects of compounding, even if this is less pronounced in a non-leveraged product.
